Weezing doesn't have the most impressive sp.atk stat anyway, and if you never invested in sp.atk then it's pointless. Just bait psychic-type pokemon and switch out into a dark-type pokemon(and use moves like pursuit) if you're that afraid. Or if you're unsure if they're switching out into a psychic-type pokemon, carry something like will-o-wisp or toxic spikes so that you can at least getting something down/cripple the opposing pokemon.
